LAMP.

Specification of Letters Patent.

Patented June 28, 1921.

Application filed March 15, 1920. Serial No. 365,766.

To all whom it may concem:

Be it known that I, CHARLES E. GODLEY, a citizen of the United States, and residing at Detroit, in the county of Wayne and State of-Michigan, have invented a new and Improved Lamp, of which the following is a moved into the lamp and the other to stopthe reflector when it has been turned a predetermined distance and to prevent the reflector from turning back to removing position.

It also consists in mounting the locking tongue on a resilient leaf, preferably sheared from the body of the headlight, so that the tongue may be swung out of engagement in. said second notch.

It further consists in the details of construction illustrated in the accompanying drawing and particularly pointed out in the claims.

In the drawings, Figure 1 is a front elevation of a lainp body and a reflector mounted therein. Fi 2 is a section on. the line 2-2 of Fig. 1. ig. 3 is an elevation similar to Fig. 1 with thereflector rotated within the lamp body to locked position. Figs. 4 and 5 are sections on the lines 4-4 and 5-5 of Fig. 3 respectively. Figs. 6 and 7 are front elevations of a lamp having a modifled form of reflector lock. Fig. 8 is a side elevation of this lamp. Figs. 9, 10 and 11 are sections on the lines 9-9, 10-10 and 11 11 of Fig. 8 respectively.

Similar reference characters refer to like parts throughout the several views.

The cup-shaped lamp body 1 shown in Figs. 1 to 5 inclusive is provided with an internal groove which results in an external circumferential bead 2, and it terminates in the cylindrical ring 3. In this groove is mounted a circumferential wire spring 4 which has a number of V-shaped ears 5 which press against the radial flange 6 of the reflector 7 to force it outward This flange 6 has a series of notches 8 through which pass the retaining pins 9 by means of which the reflector is held in position.

Tongues 11 and 12 are struck up from this flange 6 of the reflector and project from the outer side of this flange and leave notches 14 and 15 in the edge thereof. A tongue 16 extends inwardly from the ring 3 of the body and is adapted to pass through these notches. The reflector may be formed with an opening 17 and the lamp body with a lens 18, through which opening and lens the rays from the bulb 19 may pass.

When the reflector is to be mounted in the body it is turned until the pins 9 are in alinement with the notches 8 andv the tongue 16 with the notch 15. The reflector is then pushed in until the flange 6 is back of the pins 9 and the tongue 16, when it is turned until the tongue 11 contacts with the tongue 16, as shown. in Fig. 3. It is then released, whereupon the ears 5 press the reflector outward until the flange 6 presses against the pins 9 at which time the tongue 16 enters the notch 14. This prevents the reflector from turning until the reflector is again pushed back until its flange 6 is back of this tongue 16, when it can again. be turned to the position shown in Fig. 1 and removed from the lamp body. The tongue 12 prevents the reflector from being turned too far and serves to aline the notches 8 with the pins 9.

1n the structure shown in igs. 6 to 11 inclusive, slightly different details are advisable owing to the fact that there is no spring within the body to press the reflector outward. The structure here shown is adapted to be used with a lens ring and locking ring such as shown in my prior Patent No. 1,340,163, dated May 18, 1920, but this locking ring and lens ring form no part of the present invention.

The cup shaped body 21 of the lamp has a bead 23 and a circular end 22. The reflector 24 has a radial flange 25 provided with notches 26 to permit the passage of the pins or tongues 27 extending inwardly from the end 22 of the lamp body. If desired, these tongues may be struck up from the metal of the body. A second set of tongues 28 also extend inwardly,'and against them the flange 25 on the reflector is positioned. Thus far the structure is the same as that of my prior application.

In the edge of the flange 25 of the refle tor are two additional notches 29 and 30, the former having an. inclined wall 32. The end 22 of the body is sheared along the line 33 (Fig. 8) to produce a resilient keeper 34 having an inturned lip 35 which is of such a length longitudinally of the axis of the lamp that the flange 25 can never be moved below it.

When the lamp is to be assembled, the reflector is positioned in. the body, as shown in Fig. 6, with the pins 27 passed through the notches 26 and the flange 25 on the reflector against the tongues 28. The reflector is then turned to the left to the position shown in Fig. 7, the tongue 35 on the keeper 34 riding up on the inclined wall 32 of the notch 29, and moving into the notch 30 when that is reached. The tongues 27 prevent the reflector from moving out and the tongue 35 prevents it from turning until this keeper is sprung out far enough to move the tongue 35 out of the notch 30 which is readily done by pressing outwardly with any small flat object on the inner end of this tongue while the reflector is being turned sufiiciently to carry the notch 30 out of alinement with the tongue. Thereafter the reflector may be turned to normal position.

In each embodiment the lamp body is formed with retaining pins or fingers to prevent the outward movement of the reflector and the reflector is providedwith notches to permit these retainers to pass. The reflector is also formed with two notches which may be entered by a stop on the body, one of the notches serving as a passage for the stop when the reflector is placed within the body and the other notch being adapted to receive the stop and thus limit and prevent the movement of the reflector.

The sizesand proportions of the various details may all be modified by skilled lamp makers without departing from the spirit of my invention as set forth in the following claims.

I claim 1-- 1 In a lamp, the combination of a cupshaped body having a cylindrical open end,

retaining devices extending inwardly from said cylindrical end, a reflector movable into said body and having a radial flange adapted to slide within the cylindrical end of said body,'said flange being formed with notches adapted to permit said retainers on the body to pass through, said flange being also formed with two additional notches, and a resiliently mounted outwardly movable tongue extending inwardly from said cylindrical endof the body and adapted to enter said additional notches.
